Multidimensional Array via SPL

Per default any implementation of ArrayObject does not allow to use the object as multidimensional array. This snippet here implements the support:

class ArrayMultiObject extends ArrayObject
{
    function __construct($array, $flags = 0, $iterator_class = "ArrayIterator")
    {
        $objects = array();
        foreach($array AS $key => $value) {
            if(is_array($value)) {
                $objects[$key] = new ArrayMultiObject($value, $flags, $iterator_class);
            } else {
                $objects[$key] = $value;
            }
        }

        parent::__construct($objects, $flags, $iterator_class);
    }

    public function offsetSet($name, $value)
    {
        if(is_array($value)) {
            $value = new ArrayMultiObject($value);
        }

        return parent::offsetSet($name, $value);
    }
}
